My gf has a pregnancy fetish. Specifically, she fantasizes about being forceably impregnated. Recently she had a pretty good idea, she wanted me to freeze my sperm over a large period of time, then tie her up and put the frozen sperm into her and plug her pussy somehow so that it could not come out. She also wanted to be tied up so that there was no way she could get out of it.
So I spent about a month cumming into an ice cube tray and freezing them into little sperm cubes (this was her idea). Now I have about a dozen good sized ones, she wants me to push them all into her pussy, put an inflatable butt plug into her pussy and blew it up to a pretty good size so that when the sperm melts none of it can come out. Then, she wants me to tie her up on the bed with her butt in the air so that it would flow downwards toward her cervix (again, her idea)
My question is this, we only use condoms for birth control, but she insists that since the sperm is frozen that it is all dead and there is no "actual"l risk of her getting pregnant.
Is this true or is she just trying to trick me here?
